RFID for precision drilling in the airline industry

Project objectives:

We were contracted by a tool manufacturer for the airplane industry to develop an RFID system to be integrated into a new type of portable precision drilling machine.

Project background and description:

The customer serves primarily the global automotive, aerospace, energy, and general industry markets. In most traditional industries precision holes can be successfully drilled with a drill press or CNC machine but because a significant number of aircraft components are too large, too complex or too irregularly shaped to be taken to a machining center, portable precision drill motors must be taken to the plane itself. It is impractical to drill precision holes in a wing, fuselage or engine nacelle any other way. With a wide wide range of hole sizes, the critically close tolerances required of those holes and the divergent materials used in the aerospace manufacturing industry demand that these portable precision drill motors are available with a remarkably broad range of cutter speeds, feed rate combinations, and physical properties that can accommodate virtually any workspace or application.

All of the customers tools in this range are designed to be fixture mounted with torque and thrust counteracted by the fixture, not by the operator. These tools do not rely on the variable strength of manpower to push against a drill, which means they deliver greater accuracy, repeatability and consistency of hole integrity, as well as greatly reduced fatigue and risk of injury to the operator.

When drilling the thousands of precision holes in a wing, a large number of fixture segments are used and in each segment several bushings are mounted. The bushing has a bayonet locking mechanism to allow for a secure and exact positioning of the drill motor. Each bushing is fitted with a small RFID tag. The fact that most of the components to be machined are not only very expensive, but also difficult to machine materials, it is essential to knew that the right tool is used, at the right cutting speed and feed, at each particular instant.

The project solution:

We designed a small RFID reader that could be integrated into the drill motor body. The reader can control two antennas. The drill machine is of a modular design. It has a control unit to, amongst other features; also govern feeds, speeds and coolant supply. Depending on size and type of tool different nose pieces can be attached to the machine. Each of the nose pieces has a small RFID tag installed. One antenna is used to verify that the correct type and size is fitted for the job to be performed.

The second antenna is mounted at the very tip of the nose piece. It is oriented so that when the machine is securely clamped in the drill bushing, the nose antenna and the bushing tag are lined up in front of each other.

When the machine is first set under power, the reader automatically switches to antenna No.1. As soon as the nose piece has been identified and verified to be the correct one, the machine is ready to dock onto a fixture bushing. There the bushing tag ID is read and sent to the machine control unit. There the correct program is loaded and the hole is automatically drilled, using the preset ideal cutting conditions.

The result is an improved hole quality:

  • Diameter tolerance
  • Countersink depth tolerance
  • Hole finish
  • Hole straightness
  • Lack of burrs
  • No delamination in composites
  • No fiber fraying in composites
  • No metallurgical change from excess heat

Reduced cost per hole:

  • Decreased drilling time
  • Reduced number of operations for each finished hole
  • Combined drilling and countersinking into one operation
  • Self clamping attachments minimize hole to hole time

Reduced inventory & capital investment:

  • Portable equipment eliminates expensive and large stationary machines
  • Simultaneous drilling and countersinking reduces total equipment requirements
  • Self clamping significantly reduces fixturing costs
  • Modular designs reduce the number of complete backup units

Improved tool economy:

  • Exact monitoring of tool life
  • Only regrinding when needed

Frequency ranges for RFID

RFID systems are divided into 4 different operating frequency ranges, each with their own characteristics and for convenience, we have compiled some of the differences here for you:

ideal125 rfid reader and ideal125a rfid antenna

LF – Low frequency (125kHz and 134.2kHz)
The LF range is one of the oldest and most wide-spread frequency ranges for RFID. It is also one of the most globally adopted and are mainly used by assembly lines in the manufacturing industry as well as in distribution facilities where they easily can be integrated in, for example, conveyor belts. LF is used for relatively short reading distances and one of the advantages of the system is its insensitivity to water, ice and snow. An additional advantage is that the antennas are relatively easy to adapt to the needs of different applications.
The antennas for LF systems are typically composed of a coil of copper wire, if the mounting is in proximity to a metal space the wires is sound around a ferrous core. Antennas can be manufactured in many different shapes and sizes, from Ø5x18mm up to 400x400x15 mm. The LF range tags are passive and have relatively low data transfer rate.

HF – High frequency (13.56MHz)
The HF range is just as the LF range globally available for RFID applications, and like the LF systems they use near-field inductive coupling for communication and power-transfer between tag and interrogator. Even the HF tags are passive and the reading range is less than 1 m. The data transfer rate is higher than for an LF system but lower than for UHF. Another difference from LF systems is that HF systems can be implemented with anti-collision capabilities to facilitate reading of multiple tags int he interrogation zone. Due to the short reading range, this is however not often implemented to reduce cost and system complexity. HF antennas are typically made of less than 10 windings of copper, aluminium or silver coil, this makes them easy and cheap to manufacture, light and thin.
Typical uses are for smart shelves, library books, credit cards, airline baggage and asset tracking.

UHF – Ultra high frequency (433MHz and 860-960MHz)
For UHF systems, the 433MHZ range is used for active tags, while the 860-960MHz range (more commonly referred to as the 900 or 915MHz range) is used for both passive and active tags.
The reading distance for UHF systems is up to 10 meters and use far-field radiative coupling (backscatter coupling). All the UHF protocols includes anti-collision capabilities and have a higher data transfer rate than both LF and HF systems. UHF tag antennas are like HF antennas made of copper, silver or aluminium, but here deposited on a substrate and can be made very thin, less than 0.1 mm. A drawback with the UHF tags is that they cannot easily be read when mounted on objects containing water, and if mounted on metal objects the antennas need tuning for proper readings. The tags can also not be read if the path between interrogator and tag is blocked by objects of water or metal.
As a final note should be mentioned that the higher of the UHF frequency ranges (900MHz) is not uniformly regulated globally and The band size (allowed frequency usage), maximum power and number of channels used varies between different regions (North America, Europe, Japan, Australia etc.)

Microwave (2.45GHz and 5.8GHz)
Almost all tags use the 2.45GHz range at the moment. The Microwave tags are available as passive, semi-passive and active types and are usually even smaller than the UHF tags. Semi-passive tags have a reading range of about 30 meters, while active tags can be read at over 100-meter distance. The tags cost more than UHF tags but share the same advantages and disadvantages. The antennas differ in that they are directional, which makes it possible to sharper define the interrogation zone for passive and semi-passive tags and makes them easier to design for use with metallic objects. A drawback is the possibility of interference since they use the same frequency ranges as for example cordless phones and microwave ovens. Usage examples are fleet identification, highway tolls, and real-time location systems (active tags).

Industrial RFID reader with USB interface USB125

Manufacturing industries very often have press- or stamping tools, consisting of many different parts that need to be assembled in the correct order to avoid damages to the tool. For critical parts, identification on item level might be necessary. Our reader USB125 comes with a separate holder, so it can easily be attached to the work place where the assembly takes place. The critical tool parts are equipped with small glass tags (Ø2,12 x 12,2 mm), allowing an error-free identification.


A practical feature when working with stamping tools is the ability to track the tool usage. Re-sharpening of the tool can thus be kept to a minimum, prolonging the tool life and saving costs.

Our new Mini RFID Reader MR125

Identification tasks in manufacturing industries, logistics and many other areas can mostly be solved using an antenna out of our standard line of antennas. They range from 100x100x15 mm up to 400x400x15 mm. Two sizes of cylindrical antennas are also part of the standard line; M30 L70mm and M18x1 L25mm.


However, there are instances, when it would be desirable to have the reader integrated into an object e.g.a special drilling machine. This allows identification of operations on very large objects, as is the case in the Aircraft Industry. Thousands of holes have to be machined and it is important to document that the right tool has been used. The system can also register at what time the hole was drilled and how many holes have been made so that unnecessary re-sharpening can be avoided.

Although small in size (76x33x10mm) the reader can handle two antennas and many types of RFID-tags.
